ATTORNEYS Patented Jan. 31, 1939 UNITED STATES BEVERAGE COOLING DEVICE Felix Kurpiewski, Trenton, N. J assignor to The K and R Manufacturing Company, a corporation of New Jersey Application July 12, 1937, Serial No. 153,273

'7 Claims.

The invention relates to a beverage cooling device and more especially to a beer cooling system.

The primary object'of the invention is the provision of a device of this character, wherein the 5 cooling liquid is subjected to air under pressure, the liquid being confined within a chest forming a tank therefor 50 that the cooling liquid will be aerated for constant circulation while compressed air admitted to a distributor will be cleaned prior to the delivery of such air under pressure into the beverage keg or holder, the beverage or beer to be dispensed from the keg or holder being caused to flow through a cooling coil surrounded by the cooling liquid within said cabinet or tank and in this manner the air under pressure delivered to the beverage keg or holder will be subjected to purifying liquid in the operation of the system and in this manner effecting a-perfect cooling operation.

Another object of the invention is the provison of a device of this character, wherein the construction of the same is novel in its entirety so that the cooling liquid can be readily aerated and the air under pressure admitted to the beverage or beer keg or holder will be subjected to a cleaning operation for the purification of such air as the air under pressure will be intercepted by a purifying liquid during the flow thereof, the beverage or beer prior to dispensing of the same will be properly cooled or chilled in the operation of the device.

A further object of the invention is the pro- Vision of a device of this character, which is simple in construction, thoroughly reliable and efficient in operation, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawing the figure is a a fragmentary elevation partly in section of a cooling system for beverage constructed in accordance with the invention.

Referring to the,accompanying drawing in de tall, the cooling device comprises a cabinet, a

50 portion of the same being indicated at 5, and is suitably lined to provide a liquid tank 6 having a perforated removable cover or topl. Within this tank is held a cooling liquid 8, the normal level of the same being indicated at 9, and within such liquid 8 is arranged a beverage cooling coil Ill having the lead end II from a beverage keg or holder l2 and an outlet dispensing end or lead l3, respectively, the latter being preferably carried through one side of the cabinet 5 while the lead end II is carried through the bottom thereof. v

In association with the tank 6 and about the coil I is a refrigerant coil l4 having arranged therewith an expansion valve l5 at the refrigerant compressor lead It, the coil 14 being submerged in the cooling liquid 8 within the tank 6 and is about the beverage coil l0 therein.

Outside the cabinet 5 is arranged a tubiformed distributor manifold l'l having distributor connections l8 for one or several beverage kegs or holders I2 and each connection has fitted therewith a cut-off valve IQ of standard construction.

Within the tank 6 is an air cleaner 20 containing a cleaning liquid 2| and formed with a central flue 22 opening at opposite ends into the tank 6 beyond the bottom and top of the air cleaner 20. Extended into the lower open end of the flue 22 is an air cooling liquid circulator 23 while bridging the upper open end of this flue 22 is a water deflector 24, the circulator 23 being in communication with an air pump (not shown), and the air under pressure flowing through the flue 22 enters the cooling liquid 8 within the tank 6, aerates it andcauses circulation thereof.

Extended downwardly from the top of the cleaner 2U interiorly thereof into the cleaning liquid 2| is an air inlet 25 from the air pump (not shown) while leading from the interior of the cleaner 2!) at the top thereof to the distributor manifold i1 is a compressed air lead 26 for filtered air under pressure from the cleaner 20 to the manifold I'l whence this cleaned compressed air is conveyed to the beverage keg or holder l2 for dispensing purposes of the latter in a beverage dispensing system.

It is, of course, to be understood that the cooling fluid or the contents 8 can be agitated in any desirable manner through the use of mechanical devices or otherwise.

What is claimed is:

l. A cooling device comprising a liquid cooling tank, a beverage coolingcoil within said tank, a refrigerant coil within said tank, an air cleaner and cooler within the tank and environed by one of said coils, a conduit for sup-plying air to the cleaner and cooler, and a conduit for removing air from the said cleaner and cooler.

2. A cooling device comprising a liquid cooling tank, a beverage cooling coil within said tank, a

refrigerant coil within said tank, an air cleaner :1

and cooler within the tank and environed by one of said coils, a conduit for supplying air to the cleaner and cooler, a conduit for removing air from the said cleaner and cooler, and a conduit for delivering air within the tank for aerating its contents.

3. A cooling device comprising a liquid cooling tank, a beverage cooling coil within said tank, a refrigerant coil within said tank, an air cleaner and cooler within the tank and environed by one of said coils, a conduit for supplying air to the cleaner and cooler, a conduit for removing air from the said cleaner and cooler, a conduit for delivering air within the tank for aerating its contents, and an open flue extending through the cleaner and cooler and receiving the last-mentioned conduit.

4. A'cooling device comprising a liquid cooling tank, a beverage cooling coil within said tank, a refrigerant coil within said tank and about the other coil, an air cleaner and cooler within the tank and encircled by said coils, a conduit for supplying air to the cleaner and cooler, a conduit for removing air from the said cleaner and cooler, a conduit for delivering air within the tank for aerating'its contents, an open flue extending through the cleaner and cooler and receiving the last-mentioned conduit, and a water deflector crowning the said flue.

5. A cooling device comprising a liquid cooling tank, a beverage cooling coil within said tank, a refrigerant coil within said tank and about the other coil, an air cleaner and cooler within the tank and encircled by said coils, a conduit for supplying air to the cleaner and cooler, a conduit for removing air from the said cleaner and cooler, a conduit for delivering air within the tank for aerating its contents, an open flue extending through the cleaner and cooler and receiving the last-mentioned conduit, a water deflector crowning the said flue, and a manifold having connection with the cleaner and cooler.

6. A cooling device comprising a liquid cooling tank, a beverage cooling coil within said tank, a refrigerant coil within said tank and about the other coil, an air cleaner and cooler within the tank and encircled by said coils, a conduit for supplying air to the cleaner and cooler, a conduit for removing air from the said cleaner and cooler, a conduit for delivering air within the tank for aerating its contents, an open flue extending through the cleaner and cooler and receiving the last-mentioned conduit, a water deflector crowning the said flue, a manifold having connection with the cleaner and cooler, and means for supplying beverage to the beverage cooling coil.

'7. A cooling device comprising a liquid cooling tank, a beverage cooling coil within said tank, a refrigerant coil within said tank and about the other coil, an air cleaner and cooler within the tank and encircled by said coils, a conduit for supplying air to the cleaner and cooler, a conduit for removing air from the said cleaner and cooler, a conduit for delivering air within the tank for aerating its contents, an open flue extending through the' cleaner and cooler and receiving the last-mentioned conduit, a water deflector crowning the said flue, a manifold having connection with the cleaner and cooler, means for supplying beverage to the beverage cooling coil, and a connection between the manifold and said lastnamed means.
